The white 9-inch 9450 Self-Tightening Propellers for the DJI Phantom is a set of two propellers, one clockwise (CW) propeller and one counter-clockwise (CCW) propeller. By using a second generation airfoil designed with computational fluid dynamics, the 9450 gives your Phantom extra thrust and better power efficiency. Thanks to this increased thrust, performance is significantly improved in flight, especially during quick maneuvers and descent or when carrying additional payload.

The 9450 propellers allow for extra thrust and better power efficiency than the previous 9443 models.

The DJI-pioneered self-tightening design keeps each propeller securely in place during operation, by using the motion of the motor itself as a tightening mechanism.
